Use the Inter-Organization Replication tool to replicate free and busy information and public folder content between Exchange organizations. The tool allows for the coordination of meeting, appointments, contacts, and public folder information between disjointed Exchange organizations. The tool consists of two programs: the Replication Configuration program (exscfg.exe), and the Replication service (exssrv.exe). The Replication Configuration program creates a configuration file for setting the replication frequency, logging options, folders to be replicated, and accounts to be used. The Replication service continuously updates information from one server (designated as the Publisher) to one or more Exchange servers (designated as Subscribers).

Support Life Cycle Statement for this Tool The Inter-Organization Replication tool follows the Microsoft Lifecycle policy of Exchange Server 2003, which is in Extended Support since April 2009. For more information on the Extended Support phase refer to the Microsoft Support Lifecycle page.
